Drip trickle irrigation is an efficient irrigation method used in dry and semi-arid agricultural regions around the world.
The basic principle of drip trickle irrigation is to deliver water and nutrients directly to the roots of plants in the soil through a low-pressure pipeline system and drip emitters installed on a capillary tube, based on the water requirements of the crops. By replacing traditional flood irrigation and large-scale fertilization, drip irrigation system manufacturers provide a cost-effective, labor-saving, and water-conscious irrigation method that perfectly caters to today's farming needs.
The integration of water and fertilization in drip trickle irrigation achieves precise irrigation and fertilization for crops, greatly reducing water usage, protecting soil structure, reducing nutrient losses, increasing crop yields, and improving economic benefits.
As early as 1860, Germany began to experiment with underground irrigation using drainage tile. The porous irrigation tile patent applied by Charles Lee in California in 1920, which only wetted the soil around the tile, was considered the original model of drip trickle irrigation, and is known as the world's earliest drip trickle irrigation technology.
With the rapid development of the plastic industry after World War II, drip trickle irrigation technology also developed rapidly in developed countries such as Israel and the United States.
Compared with traditional surface irrigation, subsurface drip trickle irrigation can not only save 70% to 80% of water, but also save about 60% of investment, and the operating cost of irrigation is only about 30% of traditional irrigation methods such as sprinkler irrigation. The land utilization rate can increase by 3% to 5% because the subsurface drip trickle irrigation project does not require canal repair and the pipeline is buried underground.
Due to the significant water-saving and yield-increasing effects of subsurface drip trickle irrigation, it has great development potential in dry and semi-arid regions in northern China, complex terrain mountainous areas, hilly areas, deserts, sandy and saline soils. By purchasing and implementing a high-quality subsurface drip irrigation system for sale, farmers can benefit from significant water savings and increased yields, thus enhancing the potential for agricultural development in these areas.
Although the subsurface drip trickle irrigation system has significantly reduced water usage and increased yields, there are several issues that should be noted during use. The plastic film cover is difficult to degrade, so we should choose degradable film as much as possible, and the government can provide certain subsidies to promote degradable films. The exposed pipeline on the surface is too weak in aging and frost resistance, which is prone to damage, thereby increasing the user's investment cost to some extent. Therefore, it is recommended to contact the manufacturer proactively before using it in the future and choose the production pipeline with targeted improvement in utilization. The promotion of drip trickle irrigation technology still faces challenges in China due to insufficient promotion efforts, limited application in water-deficient regions, and high one-time investment.
